Gravitational lensing of one galaxy by another a rare "Einstein ring".

Don't comment just to troll or to show how impervious to knowledge you are proud of being.

I believe I came across this on a youtube channel recently.

An aside - all the sci-fi films show folks walking about on spaceships as if they are in near earth-like gravity. How does that work?

[davebro3]

not all maybe - but a lot

[Old_Geezer]

Artificial gravity.

It's sci fi.

[gingejbee]

^the clue is in "sci-fi"...science FICTION.

[ToraToraTora]

well it's sci fi so we assume that in the time portrayed they have learned to control gravity. Often wheel like structures are used and the rim turning can simulate gravity so that's more analogous to current gravitational understanding.

The graviton is essentially the theorised boson for gravity in the same way the the Higgs is the boson for mass. The latter has been discovered not yet the former but perhaps it could be instrumental in a future gravity control device.

Space news is the absolute minimum I'd expect from a company called Sky.

Great work from Euclid telescope. There are in fact about 1,000 of these "Einstein Rings" already logged but only about 100 show the rings in neat circles from our perspective. This example is "near" to us being produced by a Galaxy only some 500million light years away. The furthest logged was discovered by the James Webb telescope and is some 31billion light years away.  I wonder if on some level there is any correlation between the phenomenon known as Newton rings and the Einstein Rings.   

[ToraToraTora]

No, Newton's rings are a reflected light interference pattern, this is the bending of space time by gravity.

[Atheist]

Yeah, but Dyson spheres have surely sucked the juice out of these mad ideas.

And did Newton know about the bending of space time by gravity?

What  a brilliant scientist was Einstein, it makes me wonder what he would theorise if he were alive today, working with more advance tools of the trade. It will be interesting to see if Stephen Hawkings scientific theories will, in the future, be found to have the same impact on the scientific world.
